Galvanized Steel Grating with Smooth Plain Tooth Flat Bearing Bar
Features of Metal Bar Grating
Steel Grating is welded bearing steel bars and cross twisted bars accoring to required pitch space between steel bars by steel grating welding machines.it is a grid building material.
All gratings are made using high quality standard steel materials which exhibit good hardness and high tensile strength. It is extremely strong, durable and corrosion resistance and great anti-slip performance.
Based on where the grating will be used and its load bearing requirements, steel bars are available in a range of spacing pitch, thicknesses and heights.
